U.S. Stamp Images
The United States Postal Service’s policy is that formal, written permission is not required to use stamp images that were issued prior to January 1, 1979.
When using pre-1979 stamps you must still follow the reproduction guidelines which are as follows:
Illustrations may be in color or in black and white, and may depict philatelic items as uncanceled or canceled. When depicting uncanceled items in color, illustrations must be less than 75% or more than 150% in linear dimension of the size of the design of the philatelic items as issued. Color illustrations of canceled philatelic items and black and white illustrations of uncanceled or canceled philatelic items may be in any size.
In many cases, particularly with older stamps including those released before 1979, the U.S. Postal Service does not have information about other potential third-party ownership interests. In these cases, you would be solely responsible for identifying and obtaining permission from any other third parties that may have an ownership interest in the image.
For additional information and to obtain image files please contact the U.S. Postal Service Licensing Department.
International Stamp Images
Permission for use of international stamp images (non-USA) should be obtained directly, before use, from the entity, or entities, to whom stamp copyright belongs.
